States that legalized online sports betting since 2018 saw a roughly 10% increase in binge-drinking frequency among men aged 35 and younger who already reported binge drinking, according to new research in Health Economics.

North Korean defectors initially show higher rates of infection-related cancers like liver and cervical cancer, but their cancer profiles gradually shift toward the lifestyle-driven patterns seen in South Korea, offering a rare natural experiment in how environment shapes cancer risk.

States that enacted total abortion bans after the 2022 Dobbs decision experienced a 1.6% birth rate increase and $6.9 million in additional WIC food-assistance costs in 2023, driven by 4.3% more postpartum women and 2.1% more formula-fed infants enrolling in the program.

AI-based weather forecasting models consume at least 21 times less energy than traditional numerical models over one year of use, according to an analysis in Weather. The training phase is energy-intensive, but the speed of inference more than compensates.

Oxygen and carbon dioxide measurements across 23 mangrove systems worldwide show that tropical mangroves already experience extreme conditions during low tide. Climate projections indicate these stress periods will lengthen, potentially excluding the commercially important fish species that depend on mangroves as nurseries.

Castrated mice fed fructose developed dramatically worse fatty liver than mice with only one risk factor. The combination altered gut microbiota, raised intestinal pyruvate levels, and synergistically drove fat accumulation in liver cells, pointing to a diet-hormone interaction in male liver disease.

Researchers used scanning thermal microscopy to watch multiple conductive filaments form and dissolve inside a volatile memristor in real time, finally explaining the randomness that makes these devices useful for encryption keys and probabilistic computing.

A new review introduces a safety-level-oriented framework for polymer-based health monitors, classifying devices from noninvasive wearables to long-term implants and mapping the material properties each tier demands for biocompatibility, stability, and signal quality.

European hedgehogs hear ultrasound up to at least 85 kHz, with peak sensitivity around 40 kHz, Oxford researchers found by testing 20 animals. The discovery could lead to car-mounted ultrasonic devices that warn hedgehogs off roads, a major cause of population decline.

A randomized controlled trial of 337 adults found that the digital therapy attexis, based on cognitive behavioral therapy and mindfulness, produced clinically relevant reductions in ADHD symptoms comparable to face-to-face psychotherapy. It is Germany's first permanently listed digital ADHD therapy for adults.

Young adults with major depression show elevated ATP production at rest but reduced capacity to increase it under stress, in both brain and blood cells. The finding, the first to detect matching energy patterns in both tissues, could lead to earlier diagnosis and targeted treatments.

Among 3 million Swedes, suicide attempts clustered most strongly among sisters, with nearly four times the risk. Heritability was 42% with no sex difference, suggesting that non-genetic factors, including shared family environment, explain why women attempt suicide more often.

Among all gut bacteria tested, only Roseburia inulinivorans was positively associated with human muscle strength. In mice, it increased forelimb grip strength by 30% and converted muscle fibers to fast-twitch type II, suggesting a gut-muscle axis that could target age-related muscle wasting.

Among semaglutide drugs, Wegovy shows the strongest association with ischaemic optic neuropathy, a form of sudden vision loss. The odds are nearly five times higher than for Ozempic and three times higher in men than women, according to FDA adverse event data.

Psilocybe ochraceocentrata, a new species discovered in South Africa and Zimbabwe, is the closest wild relative of the domesticated magic mushroom P. cubensis. The two diverged about 1.5 million years ago, challenging the idea that P. cubensis arrived in the Americas with European cattle.

For the first time, researchers synthesized long noncoding RNA outside the cell and showed that three sequences reduced inflammation in human cell cultures and mice. The work opens 40,000 naturally evolved molecules as potential drug candidates.

Reducing fibrinogen, a liver-produced clotting protein deposited on pancreatic tumors, shrank primary tumors and dramatically cut liver metastases in mouse models. The goal is not to eliminate it entirely but to return elevated levels to baseline.

As AI integrates into clinical settings and the robotic nurse industry approaches $2.7 billion by 2031, researchers at Penn Nursing warn that nursing's moral agency must remain human. Algorithms can mimic compassion but cannot care in the moral sense.

When social media users see a TV show endorsed by someone from their political party, they are more likely to watch it. But racial identity complicates the picture: white Republicans report the weakest viewing intentions overall, while Black Republicans report the strongest.

A dynamic optimization model helps NGOs in three African countries schedule preventive maintenance for community handpumps, reducing downtime by 42% to 62% and, in some cases, lowering logistics costs rather than raising them.

Ochsner MD Anderson in New Orleans will offer biology-guided radiotherapy, which injects a radiopharmaceutical consumed by cancer cells and uses the resulting signals to aim radiation in real time, even as tumors shift with breathing.

Transposable elements that jumped from another fruit fly species, not small DNA errors, cause most lethal mutations in wild Drosophila melanogaster. The finding, from 21,000 fly crosses over five years, reshapes how geneticists think about harmful variation in populations.

Researchers analyzing decades of biological monitoring data from Pennsylvania streams found that conventional oil and gas infrastructure was more strongly associated with declines in aquatic biodiversity than unconventional shale (fracking) development.

A new class of aerogel biomaterial assembled from size-controlled protein microparticles allows researchers to precisely tune pore geometry, promoting rapid blood vessel growth in wounds that currently have limited treatment options.

New research presented at the Cognitive Neuroscience Society meeting shows that AI language models can accurately predict neural responses to speech in children as young as 2, while genetic studies reveal shared biological roots between rhythm disorders and dyslexia.
